Determinate Tomatoes

Many gardeners, in the beginning, may ask, what is a determinate tomato plant, as they start their beginner vegetable garden. You will find this kind of tomato plant will grow to a determined size and ripen fruits in short periods. Most often, you see this is around a length of two weeks.

As soon as the last fruits ripen and are harvested, the plant will stop growing, begin to wither, and don’t offer any new fruits in most instances.

You also find your determinate tomato plant variety classed as ‘bush’ for the reason they don’t extend their size as you progress through your growing season.

The majority of determinate tomatoes grow to heights of 4 to 5 feet. Besides this, there is not much need for pruning a tomato plant as determinate tomato plants cease to grow on their own.

Determinate tomatoes are ideal if you wish to harvest large numbers of tomatoes in one period.

Determinate tomatoes will deliver one harvest per season. Depending on the varieties you have, this can take from 7 to 14 (48 to 100 days) weeks from planting to harvest time.

Smaller varieties such as cherry tomatoes will deliver a harvest at the lower end of the period. If you grow this type, you can plant them at different times to offer you more than one period of harvesting. However, your region will influence this if temperatures drop.
